BEDSPRING BRACE.

Application filed May 6,

This invention is specifically directed to improvements in bed springsof the type embodying a rigid lower frame and a flexible upperframe, andwherein the frames are re- 5 siliently separated by a multiplicity ofcoiled springs arranged between the frames, and it is an object of thepresent invention to pro- I vide an improved brace construction betweenthe frames of a bed spring of th s type for l the purpose of stabilizingrelative movement between said frames so as to limit such movement totravel in substantially vertical planes to preclude undue lateral swaythereof and, also, to preserve at all times the proper shape andappearance of the bed spring.

With these and other objects in view, as will appear as the descriptionproceeds, the invention consists in the novel features of construction,combinations of elements and arrangements of parts hereinafter to befully described and pointed out in theappended claims. I

In the accompanying drawing:

Figure 1 is a plan view,

Figure 2 is a vertical sectional view on the line 22 of Figure 1, t

Figure 3 is a transverse sectional view on the line 3-3 of Figure 2.

Referring more particularly to the drawing the numeral 1 designates thelower rigid frame of the bed spring. This frame is composed, as usual,of a plurality of angle bars rigidly connected to constitute arectangular plane, and connected with the angle bars are a plurality oflongitudinally spaced transconnected at their ends to the frame 1. Thisframe constitutes a base for the reception of the lower end of aplurality of spirally coiled their convolutions of largest diameter arearranged in the upper ends thereof and their convolutions of smallestdiameter disposed to rest upon and are secured to the frame 1 and itscross members 2. The upper end of the springs 3 may also be connected bymeans of a plurality of short, horizontally extending.

In order to stabilize the operation of the bed springs and to confinethe upper flexible frame for movement in a vertical plane, the presentinvention contemplates the provision of an improved base constructionconsisting of a pair of cooperating units connected preferably with thecentral portion of the longitudinally extending angle bars of the frame1 and arranged generally transverselyof the frame. Each of these bracesis formed to comprise an angle bracket 6, arrangedtransversely of theframe 1 and having its outer end recessed as at 7 so that the upperhorizontal leg of the bracket may be riveted or otherwise secured to theframe 1'. The bracket 6 of each brace extends inwardly a relativelylimited distance and has pivotally secured to the vertical legs thereofas at 8 at the extreme inner end of said bracket a check link 9, whichextends diagonally upwardly and has its upper or outer end pivotallysecured as at 10 to an upwardly and inwardly ex- The upper end of thislink is pivoted as at 12 to a diagonally extending arm 13, which has itsupper end hooked as at 14 for engagement with the border wire 5.

The arm 18 extends inwardly and downwardly with respect to the springand has its lower end pivoted as at 15 to the floating link 35 16 which,in turn, intersects the link 9 and he extreme lower end of the link 16is provided with a laterally projecting stud 18, which is receivedwithin an elongated slot 19 provided I in the fixed bracket 6; verselyextending cross members 2, rigidly From the foregoing it will be seenthat a brace construction is provided wherein the upper or hook shapedend lt of the arm 13 is limited for travel in a substantially verticalline irrespectively of the relative spacing which exists between theupper and lower frame of the spring. This construction, therefore,serves to prevent lateral swaying of the spring assembly at and limitsthe travel of said assembly to vertical planes. The slot 19 serves todefinitely limit the upward movement of the brace so as to relieve thespring assembly of strain when the bed spring is lifted bodily by forcesapplied to the border wire 5. Again, the hook it serves to securelyconfine the border wire to a determined position and prevents the latterfrom twisting or bending under the influence of the springs 3 and 41 orto other pressures which are directed outwardly and laterally.- Thebrace is of simple and positive construction, does] not interfere withthe normal resiliency of the bed spring and eifectively'serves toprotect the latter when unusual forces are applied thereto. I

What is claimed is: 1. In a bed spring, a rigid lower frame, a

spaced upper frame, springs interposed be tween said frames forresiliently spacing the latter, a transversely extending bracket rigidlyconnected with said lower frame, a

.pair of cross links, pivoted to each other at a point intermediate thelength, one of said links having the lower end thereof connected by afixed plvot wlth said bracket, the other of said links having itslowerend connected part of the length of said arm and the upper end ofthe link having the fixed pivot connection with said bracket.

2. In a bed spring,in combination, a base frame, and a resilientlyspaced upper frame having a border element, an arm having the upper endthereof connected with said border element and extending downwardly andinwardly therefrom, a check link having the lower end thereof pivotallyconnected with said lower frame and arranged to extend parallel to saidarm, a floating link plvotally connected with the intermediate boint ofsaid check link and having the upper end thereof pivotally connectedwith the inner end of said arm, the lower ends of said float- Jing linkhaving a pin andslot connection with said lower frame, and a short linksec tion connected pivotally with the upper end of said check linkand'with an intermediate part of said arm.

3.1m a bed spring, in combination, a rigid base frame, an upper frameresiliently spaced and pivotally connected therewith, the upperend ofsaid second link being pivotally connected with the lower end of saidarm and having its lower end provided witha pin and slot connection withsaid bracket, and a third link having the lower end thereof pivotallyconnected with the upper end of said checklink and its upper endpivotally connected with a point intermediate of the length of said arm.

4. In a bed spring, in combination, a rigid base frame, an upperframeresiliently spaced from said base frame. and including a flexible borderelement, a brace arm arranged'within the con-fines of said spring andhaving the upper end thereof connected with said border element, a rigidtransverse support on said base frame, and a pair of crossed linkspivoted to each other approximately midway of their length, one of saidlinks having its lower end pivotally connected to the inner end of saidtransverse support, the other of said links having its lower endconnected with said support by a pin and slot connection, 'and'its upperend to the end of said brace arm, and a third link pivot-ally connectedto the brace arm and to the upper end of-the f'mst named cross link, thethird 1 link being arranged in parallel relationship with respect to thelink having the pin and slot connection. v
